1998 Freightliner FL 70 24 foot box truck 296K

This old truck has been running great and still the engine runs fine but I have started to feel some slippage with the transmission and so I don’t drive it on the freeway anymore. I am not a mechanic and so cannot tell if it is easy to fix the tranny or not so I am just going to sell it cheap. Can be seen here at my book warehouse in south Hayward on Santana st which is near Whipple. It has a liftgate but I never used it and so it probably needs some little work to get it working.
